the dash light was on, I reset it, it has not came back on ,the engine was running normalVery likely, MAF (Mass Air Flow) sensor is the culprit. You can try and clean the MAF with CRC [MAF] cleaner. If that doesn't resolve the issue, you may just have to replace the MAF sensor.
With that code set, I am assuming "check engine" light on the dashboard is on. Other than that "check engine" light, is the car driving normal and engine running normal?
